Review: needed for long runs - I’m glad I ordered this for my long runs! It holds water without leaking, easy to hold/use, no weird water taste, and great quality design.
Review: Adequate for running hydration - I bought a belt that had this collapsible flask and enjoyed it. I bought an extra. It holds an appropriate amount of liquid and is easy drink by pinching the nozzle with your teeth and suck or squeeze the bottle. However, during a run the nozzle began to slide off the attachment. Easy fix. I definitely still use. Just question the durability.
